Product Overview

ACS complete line of thermal shock chambers includes either Air-to-Air or Liquid-to-Liquid models, designed for thermal shock tests on components or complete equipment by submitting them to rapid temperature changes automatically. They are suitable for Quality Control Laboratories or in Production plants for the screening of commercial and military components.

The extreme versatility of ACS chambers allows users to carry out a wide range of tests necessary to determine thermal characteristics under the effect of two alternating extreme temperatures. lt is possible to offer standard or custom-designed models, either vertical, horizontal or “walk-in” types.

Their wide range of accessories, the large range of temperatures, the reliability of the mechanical cooling systems and the After-Sales Service Assistance contribute to make ACS chambers an essential factor for Quality ControI and Production facilities.

Control System

WinKratos Logo

WinKratos is the software developed by ANGELANTONI Industrie S.p.A. for the monitoring and supervision of ATT climatic chambers through a PC (at customer care or on request), running under Windows (XP/VISTA/7 Professional version or higher).

Through WinKratos it is possible to create test profiles (programs), launch or interrupt the execution of a test in “manual” or “program” mode, display data in table or graphic form, and generate a report showing test results.

The software is designed to control not only single chambers but a whole test lab. It can then later be “scaled” and updated, if new machines are added to existing ones, with minimal impact in terms of time and resources.
